Leaking mixer shower

[emmacagain]

Hi,

Odd problem. I have a mixer tap / shower on my bath. The ones where you can switch between the two. When I run a bath the shower head leaks. When I switch it on to shower there's no leak on the bath taps. Is this something simple I can solve myself? If so how!

With thanks
Emma

You have to remove the diverter assembly which is typically done with a thin 19mm or 22mm spanner under the knob which lifts, if it's that type. Then there are one or two rubber O rings inside you replace and lubricate with silicone grease. All those come from a plumber's merchant.
